Abstract:
In this paper, we present a new form of interaction between students and free-text scoring tools based on the use of automatically generated conceptual models. Traditionally, students have worked with free-text scoring tools by typing free-text answers to the open-ended questions shown on the system’s interface. Students could not personalize the aspect of the interface or visually acknowledge the level of progress they have made after answering the questions. In contrast, with this new form of interaction they are able to input natural language text and look at their generated conceptual model, which can be defined as a network of concepts and the relationships among them. In the conceptual model, each node has a background colour that indicates how well it has been understood by the student. The conceptual model can be represented in several formats such as concept maps, tables, charts, diagrams or textual summaries. The results of two experiments carried out with a group of studen
ts and teachers show how they like this new possibility.
